Holiday Season Makes Most of NASA Aeronautics Gifts

Temperatures are dropping, the leaves are falling, and the countdown is on to the busiest time of year for air travel around the nation.
The industry association Airlines for America predicts 24.6 million passengers will take off to visit friends and family during the upcoming Thanksgiving holiday weekend, up 1.5 percent from 2013. Sunday, Nov. 30, will be the busiest day of the year at U.S. airports.
Even if you won’t be taking to the sky anytime soon, it’s a good bet something you're using today– your cell phone, flat-screen TV – or the holiday gifts you're buying online arrived as part of the billions of tons of cargo shipped on airplanes every year in the U.S.

“It is absolutely true that every U.S. aircraft flying today has NASA-developed technology incorporated into it in one way or another,” said Jaiwon Shin, NASA’s associate administrator for aeronautics.
Streamlined aircraft bodies, quieter jet engines, techniques for preventing icing, drag-reducing winglets, lightweight composite structures, and so much more are an everyday part of flying thanks to NASA research that traces its origins back to the earliest days of aviation.
It’s the same story for the U.S. air traffic control system. Computer software tools produced by NASA to help reduce congestion from gate to gate, on the airport tarmac and along the highways in the sky, are in place at Federal Aviation Administration facilities all over the country.
“That’s why we like to tell people that NASA is with you when you fly,” Shin said.

NASA’s commitment to leadership in aeronautical innovation dates back to March 3, 1915, when the National Advisory Committee for Aeronautics – or the N-A-C-A – was formed in response to concerns the U.S. was losing its edge in aviation to war-torn Europe.
Just 12 years after the Wright Brothers’ first heavier-than-air flight, as World War 1 raged overseas, the U.S. Congress created the NACA in part to “supervise and direct the scientific study of the problems of flight with a view to their practical solution.”
Subsequent research by the NACA’s engineers at its world-class laboratories and wind tunnels led to fundamental advances in aeronautics that enabled victory in World War II, propelled supersonic flight, supported national security during the Cold War, and laid the foundation for the space age.
Although the NACA in 1958 became NASA, which assumed responsibility for space exploration, its tradition of aeronautical research endures: identifying ever more complex problems in aviation and providing practical solutions using ever more sophisticated tools.

Guided by a fresh strategic vision that organizes NASA’s aeronautical research into six new strategic thrust areas, and inspired by the upcoming centenary of the NACA's founding, the next 100 years of innovation and ingenuity will begin with ongoing efforts to design new aircraft and engines that burn less fuel, operate more quietly, and generate fewer emissions.
At the same time, working with its industry and government partners, NASA also will continue to improve and modernize the nation’s air traffic control system so it can safely handle the two times or more increase in air traffic expected in the future.
NASA research highlights scheduled to take place during the NACA centenary year include:
- Testing of a large composite structure called "PRSEUS" that was
manufactured using a new technique that shows promise for making major
aircraft components stronger, lighter and less susceptible to damage
than composite material now in use. Flight tests are taking place now of a shape-changing trailing-edge wing flap that could improve aerodynamic efficiency and reduce noise generated during takeoffs and landings.Image Credit:NASA / Ken Ulbrich
- Flight tests of a trio of technologies on Boeing's ecoDemonstrator Program, including a new air traffic control tool that promises to increase capacity along approach paths to an airport and potentially reduce passenger delays; a system for blowing compressed air across the surface of an aircraft’s vertical tail that could allow engineers to someday design smaller aircraft tails that reduce drag and save fuel; and coatings designed to reduce turbulent flow over a wing by preventing insect residue from building up on a wing’s leading edge.
- Ongoing evaluation of a computer software tool that helps airlines find better routes to fly around bad weather while their airplane is already in the sky and on its way. Tests so far involving American Airlines and the FAA already show promise the tool can help save money in fuel costs and reduce delays for passengers.
- Flight tests of a flexible trailing-edge wing flap that bends and twists during takeoffs and landings while maintaining a seamless interface with the rest of the wing. The tests will help determine if the idea is a good one for improving aerodynamic efficiency and reducing noise.
